摘要: The controlled functionalization of single-walled carbon nanotubes with luminescent sp3-defects has created the potential to employ them as quantum-light sources in near-infrared. For that, it is crucial control their spectral diversity. emission wavelength determined by binding configuration defects rather than molecular structure attached groups. However, current methods produce a variety configurations and thus wavelengths. We introduce simple reaction protocol for creation only one type defect polymer-sorted (6,5) nanotubes, which more red-shifted exhibits longer photoluminescence lifetimes commonly obtained configurations. demonstrate single-photon at room temperature expand this other polymer-wrapped further As selectivity various aniline derivatives depends on presence an organic base we propose nucleophilic addition mechanism. Covalent generally produces authors base-mediated approach selectively achieve E11* E11*- or purely emission.
